Variety of calla lily named ‘Hawaii’

ABSTRACT

‘Hawaii’ is a new variety of calla lily having beautiful multi-colored flowers and strong branching.

Botanical classification: Zantedeschia sprengeri.

Varietal denomination: ‘Hawaii’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of calla lily, botanically known as Zantedeschia sprengeri and hereinafter referred to by the cultivar name ‘Hawaii’.

‘Hawaii’ was discovered in 1997 and chosen from a selection of seedling tubers of unknown parentage in Maungaturoto, New Zealand. The first act of asexual reproduction of ‘Hawaii’ by tissue culture was performed in 1998 in Auckland, New Zealand. Subsequent asexual reproductions by tissue culture have demonstrated that the combination of characteristics as herein disclosed for the new cultivar are retained through successive generations of asexual reproduction and reproduces true to type.

The following traits have been repeatedly observed and determined to be basic characteristics of ‘Hawaii’ which, in combination, distinguish this calla lily as a new and distinct cultivar:

-   -   1. ‘Hawaii’ is more nectarine in color than ‘Red Sox’ (U.S.         Plant Pat. No. 14,063);     -   2. ‘Hawaii’ has a more rounded and larger spathe than ‘Neroli’         (unpatented);     -   3. ‘Hawaii’ has more scarlet red coloring than ‘Hazel Marie’         (unpatented), ‘Mango’ (unpatented), ‘Treasure’ (unpatented), and         ‘Hot Shot’ (unpatented);     -   4. ‘Hawaii’ has a different leaf shape than ‘Mango’, ‘Treasure’,         and ‘Hot Shot’; and     -   5. The overlapping portion of the spathe of ‘Hawaii’ is         generally incomplete and turning downwards.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety, with the colors being as nearly true as is possible with color illustrations of this type.

FIG. 1 is a close-up photograph of flowers of the new variety; and

DESCRIPTION OF THE NEW PLANT

The following observations, measurements, and comparisons describe plants grown in New Zealand under conditions which approximate those generally used in horticulture practice. The field grown plants were 16 weeks into their third growing cycle when described. Color references are made to the R.H.S. Colour Chart of The Royal Horticultural Society of London, except where general color terms of ordinary significance are used.
